Just took delivery last week on a 2014 GC Limited. It's equipped with the 8.4AN Uconnect. How do you turn off the radio??? I see you can mute it or turn the volume level down so it's not heard but is there a way to actually shut it off?

No, because it is so deeply integrated with other vehicle systems (climate control, options such as mirror dimming, easy exit seat, etc), so not able to turn it off. You can, however, mute the audio system, and/or turn the screen off.
